an object has an electric charge of +12. it loses 10 electrons. what is the new electric charge on the object?

To determine the new electric charge on the object, we need to understand that the charge of an electron is negative. The charge on the object is positive because it has a deficit of electrons. Each electron that the object loses further increases its positive charge.

Given that the object loses 10 electrons, we need to calculate the corresponding increase in the positive charge.

Since the charge of an electron is -1.6 x 10^-19 Coulombs, we can multiply this value by 10 to find the total negative charge loss:

10 electrons × (-1.6 x 10^-19 Coulombs/electron) = -1.6 x 10^-18 Coulombs

Since the object experiences a net loss of negative charge, its positive charge will increase by an equivalent amount:

Initial charge (+12) + Negative charge gain (-1.6 x 10^-18 Coulombs) = New electric charge

Thus, the new electric charge on the object would be +12 - 1.6 x 10^-18 Coulombs.
